使用嵌套的对象数组javascript在对象数组之外创建csv

const data = [
  { name: 'John', age: 28, city: 'New York' },
  { name: 'Alice', age: 32, city: 'San Francisco' },
  { name: 'Bob', age: 45, city: 'Chicago' }
];

function convertToCSV(data) {
  const csvRows = [];
  const headers = Object.keys(data[0]);
  csvRows.push(headers.join(','));

  for (const row of data) {
    const values = headers.map(header => {
      const escaped = ('' + row[header]).replace(/"/g, '\\"');
      return `"${escaped}"`;
    });
    csvRows.push(values.join(','));
  }

  return csvRows.join('\n');
}

const csvData = convertToCSV(data);

console.log(csvData);
